Argon information, including Technical Data, Safety Data and its High Purity properties, research, applications and other useful facts are discussed below. Scientific facts such as the atomic structure, ionization energy, abundance on Earth, conductivity and thermal properties are included.
 Argon is a Block P, Group 18, Period 3 element. The number of electrons in each of Argon's shells is 2, 8, 8 and its electronic configuration is [Ne] 3s2 3p6.
In its elemental form argon's CAS number is 7440-37-1. The argon atom has a radius of 188.pm and
it's Van der Waals radius is 188.pm.
Argon is non-toxic.
Air is the primary raw material used to produce argon products. Argon constitutes 1.28% by mass and 0.934% by volume of the Earth's atmosphere. Argon was discovered by Lord Raleigh and Sir William Ramsay in 1894. Argon was the first noble gas to be discovered.
